Two particles A and B are projected with same speed so that the ratio of their maximum heights reached is 3:1.If the speed of A is doubled without altering other parameters, the ratio of the horizontal ranges attained by A and B is

A particle is projected with 20ms^(-1) at 30^(@) above horizontal. Find ratio of maximum height to the range of the projectile.

Two particles are projected with same velocity but at angles of projection 35 and 55 then their horizontal ranges are in the ratio of

Two particles of same mass are project simultaneously with same speed 20ms^(-1) from the top of a tower of height 30m. One is projected vertically upwards and other projected horizontally.The maximum height attained by centre of mass from the ground will be (g=10ms^(-2))

On an inclined plane two particles A and B are projected with same speed at the same angle with the horizontal, particle A down and particle B up the plane. If the ratio of time of flight of A and B is cot theta , where theta is the angle at which B is projected measured from inclined plane, find the angle at which particles are projected.

Two projectiles of same mass have their maximum kinetic encrgies in ratio 4: 1 and ratio of their maximum heights is also 4 : 1 then what is the ratio of their ranges?

Two bodies are projected at angles 30^(@) and 60^(@) to the horizontal from the ground such that the maximum heights reached by them are equal then a) Their times of flight are equal b) Their horizontal ranges are equal c) The ratio of their initial speeds of projection is sqrt3:1 d) Both take same time to reach the maximum height.

Two particles projected at angles theta_(1) and theta_(2) ( lt theta1) to the horizontal attain same maximum height. Which of the two particles has larger range? Find the ratio of their range.

A particle is projected with velocity u at angle theta_(1) with horizontal .The ratio of range and maximum height is 4. When it is projected at angle theta_(2) with horizontal with same speed,the ratio of range and maximum height is 2.Then (tan theta_(1))/(tan theta_(2)) will be equal to
